Now, the clean-up begins. Cities in the path of the devastating tornadoes or flooding have asked the federal government for assistance, but it will be a long process for the hardest-hit areas. The Associated Press reports about 35 people who took shelter at a Louisville, Mississippi, church have nowhere to go and likely won't be able to find a residence elsewhere for a while.

In Baxter Springs, Kansas, where an EF2 left parts of the town heavily damaged, no financial assistance will be coming from FEMA, the AP said. The agency said the damage wasn't concentrated enough for the city to earn assistance following the storm.

Arkansas was the hardest-hit state on the first day of the tornado outbreak, and an EF4 tornado roared through Mayflower, Vilonia and other nearby towns. On Sunday, former President Bill Clinton toured Vilonia with Gov. Mike Beebe, and he praised the town for how well they cleaned up the week after the tornado, according to 5 News.

President Barack Obama is scheduled to tour tornado damage in Arkansas Wednesday afternoon.
